fretscpp is strongly inspired by the original FoF, reusing artwork to a large extent, with the source code rewritten from scratch. C++ instead of python should improve performance and allow easier support for features like whammy. It is playable, but some non-critical features are still missing.

iSAM is an optimization library for sparse nonlinear problems as encountered in simultaneous localization and mapping (SLAM) in mobile robotics. The iSAM library provides efficient algorithms for batch and incremental optimization, recovering the exact least-squares solution. The library can easily be extended to new problems, and functionality for often encountered 2D and 3D SLAM problems is already provided.

The j661 project provides a generic CDS (or ARINC 661 Server) in order to facilitate the understanding of the ARINC 661 standard, prototype ARINC 661 concepts and architectures, and facilitate the reuse of ARINC 661 specifications and artefacts between projects. The CDS architecture is designed to allow defining the Server behavior to be easily modified or extended. This is achieved by a modular plug-in architecture, allowing customization at runtime without changing anything in the Server core itself.

OOo4Kids is a simplified version of OpenOffice.org intended for year 7-12 students. Everything is made in collaboration with teachers and students, with the intention of contributing back to Apache OpenOffice.

hws (HomeWork Scheduler) is a curses-based homework planner. It resembles a to-do list but provides certain features specifically for students, including the ability to manage specific classes, due dates, and priorities.

javaXUL provides a simple to use XUL implementation, including CSS and JavaScript capabilities, for use in Java projects. Some uses include the embedding of an XUL stack in a Java browser and using XUL as a UI language in Java applications, including the ability to communicate with Java. It is not intended to compete with much more complete RIA offerings such as Flash, Silverlight, or javaFX. Instead it tries to leverage the expressivity of XUL in the Java development area. Compatibility with Mozilla XUL (such as the Firefox implementation) is a goal.

OwfsWeather is a package that scans and logs weather data from various One-Wire weather sensors. It uses OWFS, the One Wire File System, to communicate with the sensors. It currently supports logging of weather data to Weather Underground, a CSV file, and to an RRD database. Current hardware supported is the WSI-601 weather station from AAG, a DS1820 temperature sensor, and the humidity and barometric pressure modules from Hobby Boards.
